Compared to ther sh*t you see, this one looks good for the price since its guaranteed 4ghz (I've seen other pc's that barely hit the $500 mark sold for +$1000 which advertised 10ghz on the cpu because it had 4 cores, wtf?) But then again, I guess it would cost less if it were you who were building it. Someone would have to do the maths, I'm feeling lazy! But personally I tend to stay away from pre builts, it saps the fun of researching, buying and putting it up together I guess.

HOLY F*CK! Its only now that I see that its in GBP, now thats another story!
